"Easily exploitable and unable to resist exploitation" is perfectly fine. We're not short on writing space here.

I don’t know, sounds dumb.

"Dumb" is an insult to someone's intelligence, as if the problem is them. Ignorant is a bit closer.

But that's not actually my point to be honest, my point is that the problem is not the people who are getting screwed over. It's the people screwing them over.

The people screwing them over rely on a target rich environment.

One could not exist without the other.

Uh huh. And what do you think causes a "target-rich environment" anyhow? Just people getting dumber for no reason?

Everyone being pushed down Maslow’s hierarchy of needs due to macroeconomic and political forces, generally. Possibly by a population wide event like a pandemic too, of course. And/or religious influence.
